2 10 all whom it may concern.'

Be it known that I, yJnssn A.`B. SMITH, a citizen of the United States,residing at Stamford, in the county of F aireld and VState ofConnecticut, have invented certain chines, and particularly to means tofacilitate the insertion of a work-sheet from the 'rear of the platen;and is a division of my application No. 305,237, filed June 19, 1919,(now Patent No. 1,377 ,4416, granted May io/ei.)

Heretofore, di'liiculty has' been experienced in inserting a work-sheetfrom the rear over a pack of sheets held in the machine, especially whenthe bottom ends of the pack of sheets are near the bottom of thepapertable and a short distance from the rear feed-rolls.

To overcome the above-mentioned dithculty, the outer sheet of the pack,which may be a carbon-sheet, may be made longer to form a tab, whichprojects beyond the bottom edges of the rest of the sheets, so that thetab may lie against the rearpaper-table when the bottom edges of theother sheets are near the rear feed-rolls. Vhen the additionalwork-sheet is to be inserted around the pack in the machine, the typistlifts the tab away from the paper-table and inserts the sheet behindsaid tab; the tab thus serving to guide the work-sheet past the edges ofthe other sheets, after which it may be moved around the platen betweenthe papertable and the pack of work-sheets to the printing point.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a sectional side view of a typewriter carriage, illustratingthe utility of the invention. Y

Figure 2 is a perspective View, showing the relationship of the Varioussheets.

The invention is herein illustrated in connection with an Underwoodtypewriter carriage, which comprises a platen 1 journaled by its axle 2in end plates 3 of the platenframe, which forms part of the carriage 5,and in which it is adapted to be rotated in the usual manner.

A proof or record-sheet 8 may be joined atthe leading end by means ofclips 9 to a carbon-sheet 10 of the width of a memorandum sheet 11. Thecarbon-sheet 1() and proof-sheet S are passed together over the usualpaper-table 12, between the usual adjustable edge-gages 13, to the rearfeed-rolls 14, from which they pass forwardly and upwardly, past thefront feed-rolls 15 to the printing line. Before reaching the printingllne, the leading edges 17 may engage paperfingers 18, which extend downalmost to the feed-rolls 15, and tend to guide the record or proof-sheetto the rear of a paper-chute 19 held in front and above the platen.

'Ihe chute 19 may exert a slight pressure by its lower edge against thepack of sheets comprising the record-sheet 8 and the carbon 10 to assistin holding said pack against sliding on the platen 1, thus permittingthe feed-rolls 14 and 15 to be cast off by the usual actuating handleY(not shown). The memorandum sheet may then be inserted around theplaten on the outside of the pack. Usually, one entry is made on thememorandum sheet 11, after which it may be removed and anothermemorandum sheet inserted around the platen. In this way the entriesmade on the various memorandum sheets are copied on the record-sheet.

To prevent interference of the leading edge of the memorandum sheet wheninserting the latter, which may be obstructed by the bottom edges of thepack of sheets in the machine when said edges are between the platen andthe paper-table, the bottom edge ofthe outer sheet of the pack isextended so as to form a tab 20, which may lie in a convenient place tobe lifted away from the table 12 by the typist, so that the memorandumsheet may be inserted behind it and Slidden down over the paper-table 12and the feed-rolls 14 and 15 to the printing point and the chute 19,which locates the memorandum sheet crosswise of the record-sheet. Afterthe memorandum sheet has been adj usted relatively to the record-sheet,the feedrolls may be thrown against the platen to hold the sheetswhile-typeing. It will be understood that the Iplaten may be linespacedif more than one entry is to be made.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used Without others.

Having thus described my invention, I claim:

vl. In combination, a record-sheet to re-l eeive carbon impressions in atypewriting machine, a carbon-sheet, means to fasten said sheetstogether at their leading portions, and a tab, extending to the rearfrom said carbon-sheet beyond the end of said recordsheet, of sufficientdimensions to be convenient to grasp, to assist in introducing aWorksheet around said record-sheet.

Q. In combination, a record-sheet, a oarbon-sheet, means to fasten saidcarbon-sheet
